Crusher general working environment is bad, vibration equipment in production is unavoidable, but when the vibration device is too large, the production efficiency will affect the crusher, damaged parts, reduce the life of the device.The main reason for the crusher herein share and how to reduce the vibration of the abnormal vibration.
1. Cause member
a. off member. After a long time operation of the crusher, the raw material is an impact can cause some friction in the parts of the equipment to fall, for example, fixing bolts or badly worn parts, these parts remain in the shedding machine the inner wall of the crusher and impact vibrations.
b. loose parts. After a period of time after starting the nut bolt crusher, since clinker temperature is high, the anchor bolt rod thermal expansion and elongation may occur, loosen the nut, and the ground can not cause strong base binding, resulting in excessive machine vibration.
2. Material reason
Moisture content of materials, large hardness.If excessive moisture material, due to high water content will lead to material sticking together and stuck in an inner wall of the crushing chamber, clogging crushing chamber; hardness or other material can not be broken material into the machine, it will lead to clogging of the crushing chamber, causing vibration of the crusher.
3. poorly designed structure
a. not designed shock absorbing structure installed crusher or not the base cushion pad damping plate, when the crusher relatively stiff material, the sound vibration device will be larger.
b. member connected properly.Into the crusher, the material should be soft pipe connection, it may also cause excessive vibration device.
